Technical field to which the invention belongs 3 The present invention relates to an automatic paper feeding device for paper, and more particularly to an automatic paper feeding device for medicine bags. 5 Front The past automatic paper feeder is shown below. In Japanese Unexamined Patent Publication No. 49-67620, an automatic paper feeding device is disclosed. The automatic paper feeding device is provided with a brake pad at one end of an original document stacked on a paper feeding table. Prevents two 10 originals from being transported at one time. In Japanese Patent Application Laid-Open No. 58-69645, an automatic paper feeding device is disclosed. The automatic paper feeding device has a smaller coefficient of friction than a friction coefficient between papers by stacking the stacked papers. Board to prevent paper from being fed in a state where the papers overlap each other. 15 Problems to be Solved by the Invention However, in the former automatic paper feeding device, not only a brake pad must be provided on each original, but also a solenoid for lifting the brake pad must be provided so that the original can be fed one sheet. Sheets are ejected from the paper feeding table. Therefore, there are problems of complicated structure and high cost. 20 On the other hand, the latter automatic paper feeding device must perform the complicated operation of placing a board between paper and paper. Therefore, an object of the present invention is to provide an automatic paper feeding device which is not only simple in structure, but also reliably prevents paper sheets from being discharged repeatedly. [Summary of the Invention] 200524807 Method for solving the problem The present invention is to solve the aforementioned problem, and it is an automatic device provided with a paper feed roller that is used to automatically supply a plurality of sheets stacked in a cassette from the top sheet in order. The paper feeding device is characterized in that it is provided with 5 holding elements, the holding element is placed on the paper in the aforementioned cassette, and has a lower friction force with the paper than the paper feeding roller flexibility. According to this structure, when the uppermost paper is conveyed by the paper feed roller, the holding member also comes into contact with the next sheet to generate friction, so that the next sheet can be prevented from being conveyed together with the upper sheet. Since the holding element itself is flexible, no matter whether the thickness of the stacked paper is different, it will be closely adhered along the surface of the paper, and the same friction force will be generated, and the paper feeding caused by the paper feeding roller will be properly prevented improper. It is desirable to form a locking portion at the rear end of the holding member, and by locking the locking portion to the cassette, the holding member can be slid freely to the paper feed direction. Here, the locking portion should be locked on a guide portion for guiding the rear end of the paper provided in the cassette. According to this structure, as the paper feed roller rotates, the uppermost paper starts to move due to the friction between the paper feed roller and the paper feed roller just described. Since the uppermost layer of paper moves at the same time as the holding element placed on it, the friction between the paper feed rollers 20 and ， can be set to the optimum value. Therefore, paper can be conveyed smoothly. As described above, "" is the medicine bag, and when the thickness varies according to the occasion, it is also deformed by the "holding element W on the surface of the medicine bag, so the friction generated is the same, and the medicine bag can be carried smoothly. 200524807 The aforementioned holding element should be in the form of a sheet, and under the conductive mi made of the same material, a non-surface_suitable photo paper is formed. Select the upper and lower surfaces to make contact with the paper. [$ 施 $ 式] Embodiments of the Invention Embodiments of the invention will be described below according to the drawings. 1 and 2 show a medicine bag printing device according to this embodiment. This medicine bag printing device is equipped with an automatic paper feeding device. The printing device 3 is used to perform predetermined printing on the paper 2 supplied from the automatic paper feeding device 丨 described above. Here again, the paper end seals the end of the palatal side and presents a pouch of a certain thickness (see Figure 3). In the automatic paper feeding device 1, '5 yrs of age are detachably installed from the front in each storage room 4, and each storage room 4 is formed in a plurality of sections in the vertical direction. As shown in FIG. 5, a paper feed roller 6 is provided in each storage chamber 4. The paper feed roller 6 is driven to rotate by a motor moving element (not shown). The paper feed roller 6 is crimped to the uppermost paper 2 accommodated in the cassette 5, and the paper 2 is conveyed by the friction between the two to feed the paper. (Hereinafter, the direction facing the paper feeding direction is referred to as "front", and the opposite direction is referred to as "rear".) As shown in Figs. 4 and 5, the cassette 5 has a box shape with an open top. A locking recess 7 is formed on the front surface of the card 20 cassette 5 for the operator's fingers to lock the cassette 5 when the cassette 5 is pulled out from the storage chamber 4. A support plate 20 is provided on the bottom surface of the cassette 5, and the support plate 20 is rotatably provided around the support shaft 10 via the arm 11. The flat portion 8 on the front end side of the support plate 20 is lifted up by a spring 9. A guide plate 12 is slidably arranged on the support plate 20 in the width direction, and is set at 200524807 for guiding both edges of the paper 2 accommodated in the cassette 5. In addition, a guide protrusion 13 is formed on the upper surface of the flat portion 8 of the support plate 20 to support the central portion of the medicine bag, that is, a portion thinner than the rain-side edge portion. A guide bow | piece 14 is provided at the rear end side of the bottom surface of the card g5, and the sheet 14 is slidably arranged in the paper feeding direction, and is used to guide the rear end of the paper 2. A locking claw 15 is formed on the upper end portion of the leading piece M so as to protrude toward the front end side. Papers 2 of the same size are housed in each cassette 15 in a stack. (The size of the cassette 5 and the cassette 5 may be the same or different.). The paper 2 is held between the support plate 20 and the paper feed roller 6 which are lifted up by the spring 9 while the cassette 5 is installed in the storage chamber 4. The paper 2 accommodated in the cassette 5 is provided behind the paper feed roller 6 with a flexible sheet 16 as an example of a holding member. As shown in Fig. 7, the flexible sheet 16 is made of urethane rubber, silicone rubber, or the like, and adheres to the area of the sheet 2 other than the portion held by the paper feed roller 6. A rectangular mounting piece 17 made of a metallic material such as stainless steel is integrally formed on the rear end side of the flexible sheets 15-16. A rectangular locking hole 18 is formed in the mounting piece 17. The guide piece η is inserted into the locking hole 18. The flexible sheet 16 is slidably disposed in the paper feeding direction of the cassette 5. In the medicine bag printing device of the aforementioned structure, the paper feed roller 6 is driven by the rotary drive 20 to the receiving room 4 containing the cassette 5 and the card 5 contains paper 2 of a size that meets the prescription data. At this time, friction occurs between the paper feed roller 6 and the paper 2 lifted up by the spring 9. This frictional force is greater than the weight of the flexible sheet 16 which is in close contact with the uppermost sheet 2. Therefore, the top sheet 2 and the flexible sheet 16 are moved simultaneously with the rotation of the paper feed roller 6. Therefore, 200524807 is more stable in the conveyance state of the paper 2 than when the flexible sheet 16 is not placed. That is, when there is only the paper 2, the paper 2 may be transported obliquely due to slight differences such as the contact state between the paper 2 and the paper feed roller 6. On the other hand, when the flexible sheet 16 is placed, the influence caused by the weight will become larger. Because there are only,, the contact pressure between the sheet 2 and the paper feed roller 6 will be slightly different in the wide direction. It is different, so it will not cause any adverse effect on the conveyance of the paper 2. By the rotation driving of the paper rollers 6, the paper 2 and the flexible sheet 16 are moved, and the edge of the locking hole 18 of the mounting sheet 17 will touch the guide sheet 14 to prevent the flexible sheet. The sexual sheet 16 moves further. The frictional force generated between the paper feed roller 6 and the uppermost sheet 2 is greater than the frictional force generated by the flexible sheet 16 which is in close contact with the upper surface of the sheet 2. Therefore, only paper 2 will continue to move. Since only the upper paper 2 is moved, as shown in Fig. 6, the scoring of the flexible sheet M will land on the surface of the next paper 2 afterwards. The coefficient of friction between the paper 2 and the flexible sheet 16 is also larger than the coefficient of friction between the paper and the paper. Therefore, the next sheet 2 is prevented from moving due to the frictional force of the flexible sheet 16, and only the top sheet 2 is transported by the rotation of the paper feed roller 6. Therefore, in the foregoing embodiment, it is possible to disregard the slightly different conditions that cause the paper 2 to be conveyed by the paper feed roller 6 due to the placement of the flexible sheet 16 on the stacked paper 2 20, and the paper 2 can be removed. Good transport. Therefore, the paper 2 can be stably conveyed in a straight line, and there is no problem that the printing direction is inclined during printing. Furthermore, since the flexible element 16 can hold the next sheet of paper 2 after the start of the transport, the problem of the paper being transported in an overlapped state can also be prevented. 200524807 In the foregoing embodiment, the case where the flexible sheet 16 is used as an example of the holding element is described. However, a plurality of linear or short-rule or net-shaped flexible members may be used. Moreover, various shapes such as a sheet-like shape and a concave-convex shape may be formed on the surface. Alternatively, a certain frictional force may be generated between the sheet 2 and the paper 2 by attaching other elements 5 such as a sponge to the surface. Furthermore, the surface of the flexible sheet 16 is plated with a conductive material or impregnated with carbon, so that the adverse effects caused by the static electricity generated on the paper 2 can be eliminated. At this time, as shown in FIG. 8, by applying different conductive materials (for example, carbon and aluminum) to the upper and lower surfaces 16a, 16b, 10 may be different according to the use of paper 2 (for example, general high-grade Paper and polypropylene). Effect of the Invention As can be understood from the above description, according to the present invention, since a flexible sheet is placed on the paper in the cassette, it can be surely achieved that only one sheet of paper is fed at a time. 15 [Circular description] The first picture is the side view of the printing of the music bag in this batch.
